high speed uv erasable programmable logic device description the at22v10 and at22v10l are cmos high performance eprom-based program- mable logic devices (plds). speeds down to 15 ns and power dissipation as low as 12 ma are offered. all speed ranges are specified over the full 5 v 10% range. all pins offer a low 10 m a leakage. the at22v10l provides the optimum low power cmos pld solution, with low dc power (8 ma typical) and full cmos output levels. the at22v10l significantly re- duces total system power and enhances system reliability. full cmos output levels help reduce power in many other system components. the at22v10 and at22v10l incorporate a variable product term architecture. each output is allocated from eight to 16 product terms, which allows highly complex logic functions to be realized. pin configurations pin name function clk/in clock and logic input in logic inputs i/o bidirectional buffers * no internal connection vcc +5 v supply features high speed programmable logic device 15 ns max propagation delay 5 v 10% operation low power cmos operation speed "l" -15,-20 all others temp com./mil. com./mil. i cc (ma) 12/15 90/100 55 cmos and ttl compatible inputs and outputs 10 m a leakage maximum reprogrammable - tested 100% for programmability high reliability cmos technology 2000 v esd protection 200 ma latchup immunity full military, commercial and industrial temperature ranges dual-in-line and surface mount packages logic diagram dip/soic plcc 0023c at22v10/l 1-97

power up reset the registers in the at22v10 and at22v10l are de- signed to reset during power up. at a point delayed slightly from v cc crossing 3.8 v, all registers will be reset to the low state. the output state will depend on the polarity of the output buffer. this feature is critical for state machine initialization. how- ever, due to the asynchronous nature of reset and the un- certainty of how v cc actually rises in the system, the fol- lowing conditions are required: 1) the v cc rise must be monotonic, 2) after reset occurs, all input and feedback setup times must be met before driving the clock pin high, and 3) the clock must remain stable during t pr . parameter description min typ max units t pr power-up reset time 600 1000 ns preload of registered outputs the registers in the at22v10 and at22v10l are provided with circuitry to allow loading of each register asynchro- nously with either a high or a low. this feature will simplify testing since any state can be forced into the registers to control test sequencing. a v ih level on the i/o pin will force the register high; a v il will force it low, independent of the polarity bit (c0) setting. the preload state is entered by placing an 11.5-v to 13-v signal on pin 8 on dips, and pin 10 on smps. when the clock pin is pulsed high, the data on the i/o pins is placed into the ten registers. t dmin = 100 ns level forced on registered output pin during preload cycle register state after cycle v ih high v il low at22v10/l 1-103
